JOHN A. STONE, OF CHICAGO, ILLINOIS, ASS IGNOR TO INTERNATIONAL HARVESTER COMPANY OF NEW JERSEY, A CORPORATION OF NEW JERSEY.

CORN-HUSKER.

1 0 all whom it may concern:

Be it known that I, JOHN A. STONE, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Corn -Huskers, of which the following is a full, clear, and exact specification.

My invention relates to corn huskers, and in particular to improved ear retarder and ear alining mechanism coacting with the husking rollers in a manner whereby the ears are directed against the rolls substan tially parallel with their axes and yieldingly held in engagement therewith.

The object of the invention is to provide a mechanism simple in its construction and efiicient in operation. This object is attained by means of mechanism, one embodiment of which is illustrated in the accompanying drawings, in which Figure 1 is a side elevatio'n'of part of a corn husking machine having my invention embodied in its construction; Fig. 2 is a longitudinal section of Fig. 1 on an enlarged scale; Fig. 3 is an end elevation of Fig. 2 in the direction of the arrow; and Fig. 4 is a detached detail designed to illustrate the manner of mounting the ear retarders.

Referring to the drawings, wherein the same reference numerals designate like parts throughout the several views, the frame of the machine shown includes downwardly inclined side members 1, having vertically disposed plates 2 secured to their upper ends, 3 downwardly inclined coacting husking rollers disposed in pairs and rotatable in opposite directions, journaled in bearings carried by the frame of the machine and having one roll of each pair preferably in a plane above its coacting roll.

4 represents an angular shaft disposed transversely of the machine journaled in bearings 5 integral with arms 6 that are pivotally connected at 7 with the side members 10f the machine near the upper ends and above the huskingrollers, the bearings being received by concentric slots 8 in the plates2 in a manner permitting the shaft to'swing about the axis of the arms to a limited extent.

9 represents rotatable ear alining members or disks carried by the shaft 4, spaced apart laterally'upon the shaft and provided with oppositely disposed teeth 10 upontheir Specification of Letters Patent.

peripheries, two teeth upon each member,

the teeth and spaces alternating laterally, as

shown in Fig. 3, and the aliners being artermediate their ends upon the shaft 4 between the ear alining -members 9 having their lower ends inclined downward toward the delivery ends of the husking rolls and terminating in a flat portion 12 normally disposed in'a horizontal plane above the lower of each pair of husking rolls and having one side 13 turned downward, and the opposite side 14 upward to facilitate the passage of ears. tarders are curved upward in front of the shaft 4: and their bodies preferably fill the space between the ear alining members 9 and form an upper wall for the feeding throat leading toward the husking rollers.

15 represents a pairof rock shafts journaled in the plates 2 and spaced apart in rear of the shaft 1 toward the lower ends of the-husking rolls and each shaft carries a series of ear retarders 16 having their upper ends journaled upon the shafts and inclining rearward and downward with converging sides, having their narrow front ends turned normally in horizontal planes above the lower of each pair of husking rolls, and one side of each turned downward and the opposite side upward similar to the members 11.

17 represents depending arms secured to the rock shafts, there being one arm for each retarder, and the retarders are yieldingly connected with the arms by means of bolts 18 carrying compression springs 19 that react between a pin and washer 20 carried by the free end of the bolt and the armin a manner permitting the retarders to swing about the axes of the rock shafts to a limited'extent. The arms upon one of the rock shafts, preferably the front one, are extended above the shaft, and 21 represents rods having their rear ends slidably received by openings in the free ends ofthe extensions. and their opposite front ends connected with ear members 22 carried by the retarders 11 above the shaft 4.

23 represents compression springs carried by the free ends of theears and reactive between a pin and washer 24' and the ex- The upper ends of the retensions of the arms in a manner to yieldingly permit a rocking movement in one direction of the retarders 11 about the axis ofthe shaft 4.

The rock shafts 15 are provided at one end with upwardly turned crank arms that are connected by means of a bar 26, and 27 represents a hand lever 'pivotally connected with a fixed part of the machine and with the bar 26 in a manner whereby the rock shafts may be adjusted angularly, and 28 represents a spring controlled pawl carried by the hand lever and engaging with a toothed sector 29 in a manner to secure the lever in any desired position [of adjustment.

In operation motion is transmitted to the shaft f by means including a sprocket wheel 30 secured to one end thereof. The ears of corn are delivered at the upper ends of the husking rolls. The rotating alining members 9 engage the {ears and turn them parallel with the axes of the rolls and feed them downward against the retarders 11, the shaft 4: carrying the retarders being free to rise bodily or at either end independently to permit the retarders to accommodate themselves to variable quantities of material being delivered to the rollers. The

vnetarders yieldale'ly press the ears against the rolls and the reversely turned side wings thereof operate as supplemental alining members. The three series of retarders are jointly controlled by the hand lever mechanism and are also permitted a limited independent angular movement about their axes.

While I have, for purposes of illustration, shown and described herein a preferred form of my invention, I do not intend to be confined to the specific construction as shown, it being understood that many changes in form, proportion and assemblage of parts may be made without fdeparting from the spirit of my invention.

What I claim as new and desire to secure by Letters Patent is:
